16GB DDR4 ECC UDIMM for Supermicro Servers

This 16GB module is built for Supermicro platforms that require ECC unbuffered memory. It suits administrators expanding capacity in compatible 288-pin DDR4 servers or workstations. The single-rank alternative is not addressed here.

DDR4 2133 Speed and Platform Limits

The DDR4 2133 standard caps transfer rates at PC4-17000 bandwidth. System memory speed will follow the lowest rated module or the processor's supported ceiling. Faster DDR4 modules will downclock to this frequency when mixed.

Dual Rank 2Rx8 Configuration Decides Fit

The 2Rx8 organisation determines how the memory controller addresses the chips. Boards limited to single rank per slot or specific rank populations will not support this module. Verify the qualified vendor list before ordering.

Questions about this item

Should I choose the 16GB DDR4 2133MHz CL15 module or a different capacity for my Supermicro server?

This module provides 16GB in a single 2Rx8 UDIMM running at 2133MHz with CL15 latency; add identical modules to reach your board's maximum supported capacity.

What does the 2133MHz rating mean once the module is installed in a real system?

The module transfers data at up to 2133 MT/s; the memory controller will set the final speed to the highest JEDEC rate both the CPU and DIMM support.

How does the DDR4 288-pin UDIMM interface limit performance in practice?

The unbuffered 288-pin DDR4 interface caps transfer rate at 2133 MT/s and requires a platform that accepts ECC UDIMMs at 1.2V.
